Today’s cyclodextrin:
According to the invention, the cyclodextrin material is doped in the perovskite absorption layer, so that the crystallization orientation and crystallinity of the perovskite thin film are improved, and the photoelectric conversion performance and stability of a device are improved; as the temperature rises in the working process of the solar cell device, the cavity of the cyclodextrin is hollow, has good flexibility, can provide a deformation space after the temperature rises, is a stress slow release way, and is beneficial to improving the stability of the device. And moreover, the composite material has hydrophobicity, so that the moisture-proof performance of the perovskite can be improved.
